SAN JOSE, Calif., Sept. 18, 2013 — (PRNewswire) — Oclaro, Inc.(NASDAQ:
OCLR), a leading provider and innovator of optical communications solutions, today announced that the dual-rate 100G CFP2 LR4 transceiver, which is fully-interoperable with the 100G CFP LR4 transceiver supporting both OTU-4 and 100GbE interfaces, has joined that module in volume production. Approximately 30 customers have already qualified or are in the process of qualifying the Oclaro 100G pluggable LR4 transceiver modules. The 100G MSA-compliant CFP2 LR4 module recently completed interoperability testing with the Xilinx Virtex®-7 H580T FPGA for OTU-4 based on the OIF CEI-28G-VSR board interface specification. Both the Oclaro CFP and CFP2 LR4 modules have now passed testing for both data rates. Oclaro will be meeting with customers at ECOC, the largest European optical communications event from September 23-25, 2013 in London, UK Meeting Room MR3.

A fully-interoperable pair of CFP and CFP2 LR4 transceivers offer network equipment manufacturers the flexibility to rapidly and easily capitalize on the smaller form factor and lower power consumption of the CFP2, while offering their customers an attractive upgrade path from deployed equipment with CFP cages to increase system front panel bandwidth with higher module density and/or to lower system power consumption per 100G interface. As the CFP MSA standard continues its growth as the form factor of choice for adoption in many 100G enterprise and data center applications, Oclaro is well positioned to help customers lead this next phase of high-speed networking.

"Xilinx and Oclaro have successfully achieved interoperability between the Xilinx Virtex-7 H580T FPGA and the Oclaro 100G CFP2 LR4 optical module showing an error free connection at 28.0 Gbit/s," said Gilles Garcia, Director of Wired Communications at Xilinx. "With this achievement, together with previously demonstrated interoperability at 25.7 Gbit/s, system OEMs designing transport, networking and data center applications can now realize 100 Gigabit Ethernet and 100G OTL4.4 applications with lower cost and power, enabling either more efficient or higher density network line cards."

"We are delighted to see the interest from our customers for both our 100G CFP and CFP2 LR4 transceiver products. This confirms the value of our strategy to continuously work to reduce size and power while providing backward compatibility when possible to ease customer adoption," said Yoshikazu Era, General Manager, Oclaro Japan Module Division. "This confirms our market leadership which relies on our technology resources, vertical integration, as well as design and development expertise."
